Description

[Detailed description of the invention] This invention relates to a charging device for coke dry extinguishing equipment. When charging coke transported in packets into a furnace, the particle size distribution on the charging surface The aim is to improve the sediment distribution.

The conventional charging device is explained with reference to FIG. 1.
This is a charging device with a conventional structure, and shows a state in which coke is charged using a coke packet with the lid opened.

In the figure, 1 is a cart that moves in the horizontal direction.
At the top, an upper hopper (receiving hopper) 2 and a lower hopper 3 for charging raw materials, and a canopy 4 for when raw materials are not charged are arranged side by side and are used selectively as appropriate.

5 is a hydraulic cylinder that moves the trolley 1 and operates a link mechanism 6 to raise or lower the canopy 4 as appropriate;
Also, the sealing mechanism 7 of the lower hopper 3 is moved up and down.

(Details omitted) That is, in the state shown in FIG. 3 is mounted on the charging port 9 of the furnace top 8 via the seal mechanism 7, and is in a state where coke can be charged.

(Incidentally, 10 is a coke packet, and 11 is a bottom lid of the coke packet 10.) When charging is completed, the cylinder 5 and the link mechanism 6 lift the sealing mechanism 7 of the hoppers 2 and 3 (details are omitted). At the same time, the cart 1 is moved to the left in the figure, and when it comes to a fixed position, the canopy 4 is lowered to cover the loading port 9.

When charging coke with the charging device configured as described above, no measures are taken to control particle size distribution, so
The charging surface distribution has an inverted V shape with fine particles at the center and coarse particles at the periphery.As a result, the cooling gas flow in the cooling chamber has a strong tendency to be a peripheral flow, and furthermore, because the plastic device is located in the furnace core, the cooling gas flow is Heat transfer with the surface of coke particles is extremely ineffective, resulting in an increase in the amount of cooling gas and chamber volume, which is a major problem in terms of equipment investment.

Therefore, in order to stop the decline in cooling efficiency caused by the single pattern of inverted V-shaped central fine grains and peripheral coarse grains found in these conventional equipment, the present invention has been developed using a V-shaped (or M-type) system with central coarse grains and peripheral fine grains. The object is to provide a charging device that ensures distribution.

Next, the present invention will be explained based on an embodiment shown in the drawings.

(See Figure 2) (Description of the cart, canopy, and mechanism for driving (opening and closing) them, which are the same as the conventional structure, will be omitted.) 12 is a bell for distributing raw materials, and the bell inside the furnace top 8 is located near the central offshore area. is fixedly supported via a support 13.

Both the raw material distribution bell 12 and the support 13 have a water-cooled structure in consideration of heat resistance.

As the water cooling structure of the material distribution bell 12, for example, a jacket structure 14 as shown in FIG. 3 is adopted.

The supports 1 to 13 pass through the furnace wall of the furnace top 8.

That is, a manhole 15 is formed on the furnace wall and supports 1 and 1 are formed.
The end of No. 3 communicates with the outside.

When the raw material distribution bell 12 is damaged, it is pulled out from the manhole 15 side with a winch and replaced.

Therefore, the manhole 15 may be formed in one of the furnace walls, and the other may be simply a through hole 18.

In addition, 16. 17 is a cooling water supply and drainage pipe.

The bell in this invention is a general term for an axially symmetrical vertebral body, and for example, a bell as shown in FIG. 4 can also be used.

FIG. 2 shows the charging of coke, in which the charged coke collides with the raw material distribution bell 12 and is distributed to the furnace wall to ensure proper distribution.

During charging, the hopper 2 is evacuated together with the trolley 1 by the cylinder 5 via the link mechanism 6 shown in FIG. 1, and the canopy 4 is lowered to seal the charging port 9. .

As described above, according to the present invention, the desired V-shaped distribution, that is, the center coarse grain and the peripheral fine grains, can be obtained despite the extremely simple structure.
This has an extremely large effect on improving thermal efficiency.
